Biscuit-base bakers
If a recipe specifies plain digestives by weight, compare that amount with the pack before deciding whether two packets would be useful. McVitie's cheesecake recipe, for example, calls for 240 g of crushed Original Digestives.
Who is choosing these biscuits?
Bakers who also pack lunchboxes
Two full-size packets serve a different purpose from individually wrapped biscuits. Check the inner-pack format if you want to carry single biscuits, and note that NHS lunchbox guidance suggests alternatives to biscuits and chocolate for regular packed lunches.
Households managing food allergies
Check the ingredients and precautionary warnings for everyone who will eat the bake or biscuit. Ordinary, vegan-labelled and free-from digestives can carry different warnings.
What should you check before buying?
Start with the recipe and the people who will eat the biscuits, then choose a pack format that also works for any biscuits left over.
| Priority | What to check | Your needs |
|---|---|---|
| Baking quantity | Compare the recipe's biscuit weight with the net weight and biscuit type. McVitie's cheesecake recipe specifies 240 g of Original Digestives; Ocado lists an Original twin pack at 2 × 315 g, while Sainsbury's lists a different 2 × 360 g format. | I want enough plain biscuit for the base without treating every pack labelled “twin” as the same quantity. |
| Portion format | Check whether the pack contains full-size inner packets or individually wrapped biscuits. Ocado lists the M&S coated digestives as six individually wrapped biscuits, a different product from a plain baking twin pack. | If I am carrying single biscuits, individual wrapping matters more than having two larger packets. |
| Ingredients | Read the specific product's ingredients and precautionary allergen statements. Sainsbury's lists a gluten- and milk-free digestive with a nut-allergy warning; Asda's vegan-labelled digestive carries a may-contain-milk warning. | The finished bake or lunchbox biscuit needs to suit the person eating it, not just match a broad label such as “vegan” or “free from”. |
| Leftovers | Consider how many packets you will open. Follow the pack's storage instructions: the M&S, Tesco and Asda plain-digestive listings specify an airtight container after opening. | When I bake on separate days, I would rather open only the packet I need now and store any leftovers as directed. |
Common pack-format mistakes
-
Assuming a twin pack contains single portions
Ocado describes McVitie's Original twin pack as two 315 g packets, whereas its M&S coated-digestive listing describes six individually wrapped biscuits. They answer different carrying and baking needs.
Read the description of the inner packs before choosing biscuits for both a recipe and lunchboxes.
-
Comparing twin packs by packet count alone
Ocado lists a McVitie's Original 2 × 315 g pack, while Sainsbury's lists a 2 × 360 g pack. A recipe specifies the biscuit quantity it needs by weight.
Check the net weight and whether the biscuits are plain before matching a pack to your recipe.
-
Using one dietary label to answer every allergy question
Asda's vegan-labelled digestives may contain milk. Sainsbury's says its gluten- and milk-free digestives are unsuitable for people with a nut allergy because of manufacturing methods.
Check the ingredients and precautionary statements on the physical pack for everyone who will eat the biscuits.

Digestive twin packs on Joybuy
These two McVitie's twin packs suit different uses: Original Digestives are the plain option to compare with a biscuit-base recipe, while the Dark Chocolate variant is a coated biscuit rather than a substitute where the recipe calls for plain digestives.

Questions about baking and storage
How many digestives should I buy for a biscuit base?
Start with the weight in your recipe, then compare it with the pack's net biscuit weight. McVitie's cheesecake recipe uses 240 g of crushed Original Digestives, while the Original twin pack listed by Ocado contains 2 × 315 g.
How are digestives prepared for a cheesecake base?
Follow the recipe you are making. McVitie's cheesecake recipe says to crush its Original Digestives, mix them with melted butter, press the mixture into the base and chill it before adding the filling.
How should I store biscuits left after baking?
Follow the instructions on your pack. The M&S, Tesco and Asda plain-digestive listings advise keeping the biscuits in a cool, dry place and using an airtight container after opening.
Is every free-from or vegan digestive suitable for someone with an allergy?
No. Sainsbury's warns that its gluten- and milk-free digestives are unsuitable for people with a nut allergy because of manufacturing methods, while Asda's vegan-labelled digestives may contain milk. Check the physical pack for the person who will eat them.
Can I compare twin packs by the number of packets?
Compare net weights as well as packet counts. Ocado lists a McVitie's Original 2 × 315 g pack, whereas Sainsbury's lists a 2 × 360 g version, so both contain two packets but different biscuit quantities.
